See Figs. 44-45 for an alternate embodiment.), the power input port is disposed within the device body (Baarman, This configuration is not illustrated but inherent in a wireless charging device as being incorporated into one housing or multiple housings based on the physical design constraints. See Figs. 44-45 for an alternate embodiment.), a portion of the power input port is exposed outside the device body (Baarman, Fig. 1, As illustrated.), and the lifting assembly is arranged between the main board and the magnetically attractable transmitter coil structure, wherein the main board is electrically connected with the power input port and the magnetically attractable transmitter coil structure (Baarman, Fig. 45, As illustrated, but does not label each part individually.). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Baarman et al. U.S. PGPub 2013/0113423 A1 (hereinafter Baarman) in view of Trice et al. U.S. PGPub 2024/0213801 A1 (hereinafter Trice). Regarding Claim 8, The teaching of the Baarman reference discloses the claimed invention as stated above in claims 7/6/4/1, but does not teach the supporting element being a scissors-type support. Trice, however, teaches wherein the movable supporting element is a scissors-type supporting element (Trice, Fig. 4, Element 124, “scissor mechanism”; Para. [0039]). Absent of showing criticality to use a scissors-type support, it would have been an obvious matter of design choice to use a scissor-type support based on desirability, since applicant has not disclosed that this type of support solves any stated problem or is for any particular purpose and it appears that the invention would perform equally well with other support types and would be at the user’s discretion to use the support type desired. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Azancot et al. U.S. Patent 8,283,812 teaches a wireless charging device with a power transmission coil moving up and down, but retains the coil within the housing. Fetterman et al. U.S. Patent 10,283,996 teaches a wireless charging device with a transmission coil which moves to better align the two coils using magnetic attraction.
